19 16 Dr. and Mrs. Sun Yat-sen, the father of our country, were watching the tide in Haining, and the tide was surging all the way. At that time, it coincided with the death of Yuan Shikai, and there was a glimmer of hope for the future of the country and the nation. Dr. Sun Yat-sen wanted to take this opportunity to achieve something big, and hoped that the cause he led would move forward like this tide and achieve something big, and he happily wrote down the four characters "Like a tide rushing". Therefore, the tide is the beginning of hope, which means that the whole process should go forward as bravely as the tide, and no difficulties and obstacles can stop it. Dr. Sun Yat-sen has such lofty aspirations. Shouldn't you and I after 90 inherit this great ideal and mind?
